In the previous issue, we talked about the operation steps of laser cutting equipment for cutting metal. Proper operation of metal laser cutting machines can fully utilize their excellent cutting efficiency, and they can effortlessly handle even thick metal materials. Today, let’s talk about how many people overlook the principles and shutdown steps of laser cutting machines.
Principles of Laser Cutting Machine
Laser cutting machine is a machine that uses a focused high power and high energy density laser beam to irradiate a workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, it uses high-pressure and high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the purpose of cutting the workpiece open. And because the laser beam is cut from top to bottom during the cutting process, the cut slag and other residues will be sprayed below the cutting machine instead of piling up on the cutting piece.
The benefits of using laser cutting machines correctly
1. Higher cutting accuracy and precision: Laser cutting machines can provide very high cutting accuracy, which is crucial for manufacturing parts that require precise dimensions.
2. Higher quality edges: Laser cutting machines can produce very neat and smooth edges without the need for subsequent processing.
3. Narrow incision width: Laser cutting can achieve very narrow incision width, which is very useful for manufacturing complex shaped parts.
4. Smaller heat affected zone and less material deformation: Laser cutting is a non-contact processing method, resulting in very small heat affected zone and minimal material deformation.
5. Reduce material pollution and waste: Laser cutting is a very environmentally friendly processing method that does not produce a large amount of waste and pollution.
6. Reduce maintenance costs: The design of laser cutting machines is simple, with low maintenance costs and long service life.
It is precisely because of the cutting advantages of laser cutting machines themselves, combined with correct usage methods, that the cutting ability of laser cutting machines has been fully utilized, and their cutting performance has been recognized by the industry. So now laser cutting machines are widely used in many industries, such as automotive manufacturing, aerospace, electronic equipment manufacturing, etc.
